3.2 TRAINING DELIVERY

The delivery of training should adhere to the design of the curriculum. Delivery shall be guided by the 10 basic principles of competency-based TVET:

The training is based on curriculum developed from the

competency standards; Learning is modular in its structure; Training delivery is learner-centered and should

accommodate individualized and self-paced learning strategies;

Training is based on work that must be performed; Training materials are directly related to the competency

standards and the curriculum modules; Assessment is based in the collection of evidence of the

performance of work to the industry required standard; Training is based both on and off-the-job components; Training program allows for recognition of prior learning

(RPL) or current competencies; Training allows for multiple entry and exit; and Training programs are registered with the UTPRAS.

The competency-based TVET system recognizes various

types of delivery modes, both on and off-the-job as long as the learning is driven by the competency standards specified by the industry. The following training modalities may be adopted when designing training programs:

The dualized mode of training delivery is preferred and

recommended. Thus programs would contain both in-school and in-industry training or fieldwork components. Details can be referred to the Dual Training System (DTS) Implementing Rules and Regulations.

Modular/self-paced is a competency-based training

modality wherein the trainee is allowed to progress at his own pace. The trainer facilitates the training delivery.

Peer teaching/mentoring is a training modality wherein fast

learners are given the opportunity to assist the slow learners.

Supervised Industry Training or On-the-Job Training is an

approach in training designed to enhance the knowledge and skills of the trainee through actual experience in the workplace to acquire specific competencies prescribed in the training regulations.


70

Distance learning is a formal education process in which

majority of the instruction occurs when the students and instructor are not in the same place. Distance learning may employ correspondence study, or audio, video or computer technologies.

Project-based instruction is an authentic instructional

model or strategy in which students plan, implement and evaluate projects that have real world applications.

3.3 TRAINEE ENTRY REQUIREMENTS

This section specifies the qualifications of trainees and educational experience. Other requirements like health and physical requirements are also stated. Passing entry written examinations may also be indicated if necessary.

30) Supervised Industry Training – similar to on-the-job training – an

approach in training designed to enhance the knowledge and skills of the trainee through actual experience in the workplace to acquire specific competencies prescribed in the training regulations.

31) Thermostat Expansion Valve (TXV) – a refrigerant control valve

connected before an evaporator that regulates flow of refrigerant. Operated by temperature and pressure, and reacts to the degree of gas superheat at the evaporator outlet through a feeler bulb

32) Transport Air-conditioning Unit – refers to an air-conditioning unit driven directly from the turning axle of the vehicle when they are in motion, or by the vehicle engine itself, or by a separate gasoline/diesel engine and/or electric motor mounted on the same vehicle. It covers the land and marine/sea transports.

33) Troubleshoot – the process of analyzing system defect or malfunction

34) Vacuum – pressure lower than atmospheric pressure measured in inches

of mercury. Complete vacuum is 29.92 in. mercury or at least 500 microns

35) Water Treatment – the use of chemicals in water to prevent corrosion, formation of scales, algae growth and formation of slime

36) Window Type Air-conditioning Unit – is a self-contained air-conditioning

unit house in a single casing mounted in a wall or window opening 37) Workmanlike-manner – quality of work within the accepted industry

standard
